Uniform hierarchical frameworks patterned by movable magnetic microparticles.

Inspired from the ancient movable type printing, we proposed a three-dimensional tunable method for the replicable patterning of uniform patterned framework. Different sized magnetic particles were utilized as the "type-heads" for patterning. The patterning area can be precisely defined by using commercial inkjet printer. Various materials, from multicomponent inorganic structures to well-defined microporous polymers, can be readily processed by this general strategy. As a practical example, we designed and constructed an intelligent multilevel hierarchy with versatile protective capabilities.
